Abstract (en)

[origin: US2018255937A1] Various systems and methods for adjusting the firmness of a spring mattress are described herein. Inflation elements having fingers may be coupled with a spring layer of a mattress to provide for inflating or deflating the fingers in the interstitial spaces defined by a group of springs of the mattress. Increasing the fluid pressure inside the fingers increases the lateral pressure on the springs. The increase in lateral pressure in turn increases the force required to compress the springs, ultimately resulting in increasing the firmness of the mattress. Conversely, decreasing the fluid pressure inside the fingers decreases the lateral pressure on the springs, which decreases the firmness of the mattress.
